AA10 (formerly CBM33). The enzymes in this family were originally classified as chitin-binding proteins (CBM33); Vaaje-Kolstad et al. have shown that these proteins are in fact oxidative enzymes [PMID - 20929773]. They are now reclassified in the AA category of CAZy. Because a significant literature is associated with the old name CBM33, we recommend to describe these enzymes as "AA10 (formerly CBM33)".
